New Zealand bowling coach Allan Donald feels his team's quarterfinal clash with South Africa would be a battle of nerves and the side which handles pressure better will have the last laugh on Friday.
South Africa topped Group B with five wins in six matches, while New Zealand finished fourth in Group A with four wins, losing matches to England and Sri Lanka.
"The thought that your World Cup will be over if you slip up just once is enough to make everybody nervous and the team that wins will be the one that handles pressure the best," said Donald.
The former South African pacer said New Zealand have better record in the World Cup against the Proteas and exuded confidence that his team will be able to defeat Graeme Smith's men on Friday.
"We are confident we can beat South Africa and I know most of our players are delighted that we are playing against them in the quarter-final," Donald, who took 330 Test and 272 ODI wickets for South Africa, said.
"On paper, they may be the favourites, but we have a superior record in major tournaments," he added.
New Zealand have won in three of their five World Cup meetings against South Africa, including a five-wicket victory in the Super Eights round of the 2007 edition.
